摘要

A fingerprint identification display panel includes: a substrate; a plurality of sub-pixel regions including a plurality of first, second sub-pixel regions. A first driving circuit and a first light-emitting unit electrically connected thereto are sequentially disposed on the substrate and located in the plurality of first sub-pixel regions. A light shielding layer having through holes are disposed on the substrate. A plurality of light detection units are disposed at a side of the light shielding layer adjacent to the substrate, and corresponds to through holes one by one. At least one through hole is disposed in the second sub-pixel region, and a ratio of an area of an orthographic projection of the through hole on the substrate to an area of an orthographic projection of the second sub-pixel region on the substrate is greater than or equal to 30%.
